GAS-SAVING APPLIANCE.

Specification of Letters Patent.

Patented. Oct. 30, 1906.

Application filed November25, 1905. Serial No. 289,029.

To all whom, it nuty concern:

Be it known that I, SPIRIDON J. JEHA, a citizen of the United States, residing at Swissvale, in the county of Allegheny and 5 State ofvPennsylvania, have invented or discovered new and useful Improvements in Gas-Sav'ing'Appliances, of which the following is a specification.

My invention relates to devices for use IO with gas-burners; and its object is to provide an auxiliary'device to be used in place of the ordinary cover or lid of a gas or similar stove whereby the combustion will be made more nearly perfect and the heat generated be r 5 saved and economically distributed.

Referring to the drawings, Figure 1 is a vertical section of my invention shown in place on the top of a stove; Fig. 2, a lan thereof; Fig. 3, a half-plan of an auxi iary device for use in connection with the devices shown in Figs. 1 and 2; and Fig. 4, a crosssection on the line IV IV of Fig. 3, a portion of the device of Figs. 1 and 2 being shown in connection therewith. Y

2 On the drawings, 1 represents a portion of the top plate of a gas or similar stove, and 2 the annularportion of a common two-part stove-lid, the circular or central portion being omitted, but fitting on flange 3 in the opening o 4 in the portion 2.

5 represents a burner located beneath the opening 4 and may be a gas, gasolene,.or s milar burner.

6 is the outer drum or casting resting on the top of the stove. It has preferably a circular bottom 7, from which the casting rises and curves inwardly, as shown at 8, until it attains the desired height, and then it extends horizontally, as shown at 9, toward 4o cular opening 10. Between the opening .10 and preferably the curved portion 8 I provide a number of wedge-shaped openings 11, which may be considered as formed by a number of arms 12,- extending inwardly radially to the rim 13 of the opening 10.

Extending downwardly from the top 9 between the rim 13 and the outer ends of the o enings 12 is the cylindrical inner drum 14 5 w ich fits into the o ening 4 and rests upon the flange 3 when t e ap liance is properly placed on the stove 1, tfie bottom 7 then resting on the top of the stove, as shown on Fi 1. The drum 14 is provided with the he es 15, which connect together the space the center thereof and terminates at the cirwithin the drum 14 and the annular space between the drums 6 and 14. I When it is desired to heat or cook material which is liable to burn when the containing vessel is subjected to the direct heat of the 6'6 burner, the device shown in Figs. 3 and 4 may be used. It consists, preferably, of a disk 16, having some means, as the circular rib 17, which enters the opening 10, as shown on Fig. 4,'to kee it from being accidentally 5 shoved off from t e top 9. The upper side of the disk is rovided with the inner annular rib 18 and tlie outer annular rib 19, the latterbeing preferably at the edge of the disk. These ribs are connected together by several radial ribs 20, which form, with the annular ribs 18 and 19, the wedge-sha ed passages 21. The disk is preferably rovi ed with numerous openings 22, whicfi lead to the annular space between the two drums 6 and 14. 7 5 A cooking vessel being placed on the top 9 and the burner 5 being ignited, the burning gases extend up in the drum 14, where they are somewhat confined and thoroughly mixed with air, a portion of the gases passing through the openings 15 and in the annular space between the drums, where they are stillconfined and caused to escape through the o enings 11 into contact with the said vessel? The cylinder 14 is substantially evenly heated on bothsides, and will therefore retain its shape. The outer drum 6, having the curved portion 8, allows no angle at the top to form a dead space, as the gases touching it will readily slide along it and out 6 at the top.

When the disk 16 is placed onthe top 9 and the cooking vessel placed on the former, the flames do not directly strike the vessel, but are caused to pass through the holes 15 and out beneath the disk. The bottom of the vessel will be heated by conduction through the upper ribs and by the contact of the hot gases or air in the spaces between the ribs. Thus there will be but little lia- 10o bility of burning anything in the vessel. A large saving of gas will be effected, as but little will be required, for only moderate heat will be necessary when the disk is used.

Having described my invention, I claimto 5 1. In a gas-saving appliance, a stove-to with an opening therein, a burner beneatli the opening, a erforated drum seated in the same, a secon drum surrounding the first drum and resting on the stove-top, a disk re- 1 IO movably adapted to be laid on said drums, and ribs in the upper face of the disk.

2. In a gas-saving appliance, a stove-to with an opening therein, a burner beneat the opening, a erforated drum seated in the same, a secon drum surrounding the first drum and resting on the stove-top, a disk removably adapted to be laid on said drums, and ribs in the upper face of the disk, there being openings near the margin of said disk communicating with the annular space be- 1 tween the drums.

3. In a gas-saving appliance, a stove-to with an opening therein, a burner beneath the opening, a erforated drum seated in the same, a secon drum surrounding the first drum and resting on the stove-top, a disk removably adapted to be laid on said drums, ribs in the upper face of the disk, and means on the disk to hold it in place on the drums.

4. In a gas-saving appliance, two drums, one within the other, a top late connectin them together and having tiherein a centrai opening, a disk removably ada ted to rest on said top plate, and having a ri in said openmg.

5. In a gas saving appliance, a drum ada ted to be seated on a stove and provided wit 1 openings therein, and a series of ribs on said drum extending toward the center thereof but having their inner ends arranged around a central opening in the top of the appliance.
